OpenTracker1+ SMT Schematic

OpenTracker1+ SMT (OT1+ SMT) - Assembled and tested OpenTracker+ surface-mount (SMT) board. This version of the OT1+ is perfect for installation inside a radio or any other application where size and weight are a concern. Without pins installed, the board measures 1.22 x 0.72 x 0.2" (31 x 18 x 5 mm).

All off-board connections are through a double row of holes, in a standard 24-pin DIP footprint. Two pin header strips are provided (not installed) to allow the board to be mated with another PCB or installed in a solderless breadboard.

There is no on-board connection between the regulator output and the 5 volt supply. This allows the regulator section to be bypassed if an external 5 volt source is available. To use the regulator, either connect the REGOUT and 5VIN pins externally or place a small blob of solder on the two jumper pads on the bottom of the PCB.

When the telemetry option is enabled, the device will transmit an APRS telemetry packet containing 8-bit analog values for inputs ADC1-5 and digital values for inputs T1CH1 and ADC6-9
